Review on πŸ”Œ Enhanced Ford OEM Finewire Platinum Spark Plugs - New Set of 8 - Updated Design by Patrick Pearson

Revainrating 1 out of 5

2005 Mustang GT for spark plugs

One post said they were made in Mexico, wherever they were made Motorcraft made a mistake. Why? The cathode looks welded, not a solid piece. All the talk about them making it one piece (sp547) over the original (sp515) to avoid breaking the fork in the head is a good idea, but the 547 forks are clearly crap and suck power, once they are installed. Attention 2005 Mustang owners, stick to the stock SP515 and up to 25 ft-lb of torque. Look for the right picture sp547. The class is dissolved.

Pros
  • Delivery was very fast
Cons
  • Negative impression
